Welcome to the UCSC Genome Browser website.
This site contains the
reference sequence and working draft
assemblies for a large collection of genomes. It also
provides portals to the
ENCODE and
Neandertal projects.

We encourage you to explore these sequences with our tools.
The
Genome
Browser zooms and scrolls over chromosomes,
showing the work of annotators worldwide. The
Gene
Sorter
shows expression, homology and other information on groups
of genes that can be related in many ways.
Blat
quickly maps your sequence to the genome. The
Table
Browser provides convenient access to the underlying
database.
VisiGene
lets you browse through a large
collection of in situ mouse and frog images to
examine expression patterns.
Genome
Graphs allows you to
upload and display genome-wide data sets.

The UCSC Genome Browser is developed and maintained by the
Genome Bioinformatics Group,
a cross-departmental team within the Center for Biomolecular
Science and Engineering (CBSE)
at the University of California Santa Cruz
(UCSC).
If you have feedback or questions concerning the tools or
data on this website, feel free to contact us on our
public mailing list.

28 New Vertebrate Assemblies!

Over the past several weeks, we have released 28 new vertebrate assemblies on the
public Genome Browser website, featuring 22 new species and 6 assembly updates.
These assemblies were added to support the 60-species Conservation track on the
latest mouse assembly (mm10/GRCm38). Several of these species were originally
sequenced and assembled for the Mammalian Genome Project (Lindblad-Toh
et al., Nature 2011)*.

Our sincere thanks to the many organizations who contributed to the release
of these datasets. We'd also like to acknowledge the Genome Browser
staff who worked on this release: Hiram Clawson, Chin Li, Brian Raney,
Brooke Rhead, Steve Heitner, Pauline Fujita, Luvina Guruvadoo, Greg Roe, and
Donna Karolchik. Please see the Genome Browser
credits page for complete acknowledgment
information and data use restrictions. All datasets may be downloaded from our
ftp server or
downloads page.

We regret that we don't have the resources to support the many other
genomics research communities who would like us to visualize their data
in our browser. However, we can provide you with information for setting up
your own browser or track hub to display your data, as well as links to
other visualization resources on the web that are specific to your
genome of interest. Feel free to contact our
mail list for more information.

The UCSC campus will be closed for the holidays from December 22, 2012 through
January 1, 2013. The Genome Browser will still be available;
however, our backup systems will be offline for two days, December 27 and 28.
During this time if we experience any issues, associated fixes are likely to be
delayed. The help desk will also be minimally staffed during this period. We will
be monitoring the mailing lists for urgent messages, but the bulk of the questions
will go unanswered until early January.

dbSNP 137 Available for hg19:
We are pleased to announce the release of four tracks derived
from dbSNP build 137, available on the human assembly (GRCh37/hg19).
dbSNP build 137 is available at NCBI. The new tracks contain
additional annotation data not included in previous dbSNP tracks,
with corresponding coloring and filtering options in the Genome
Browser.

New UCSC Genes Track Released for Mouse:
We're happy to announce the release of a new UCSC Genes
track for the GRCm38/mm10 mouse Genome Browser.

The sequence and annotation data displayed in the Genome Browser
are freely available for any use
with the following conditions:

Genome sequence data use restrictions are noted within the
species sections on the Credits
page.

Some annotation tracks contributed by external collaborators
contain proprietary data that have specific use restrictions. To
check for restrictions associated with a particular genome assembly,
review the database/README.txt file in the assembly's
downloads directory.

The UCSC, Ensembl, and NCBI browser and annotation groups
have established a common set of minimum requirements for
public display of genome data made available after Spring
2009, described
here.

The Genome Browser and Blat software are free for academic,
nonprofit, and personal use. A license is required for commercial use.
See the Licenses page for more information.

Program-driven use of this software is limited to a maximum of one
hit every 15 seconds and no more than 5,000 hits per day.

Browser software, database, genome assemblies, or release cycles,
